Venom not stopping Spider-Verse champs from evading

I was doing Act 5.2.3 and I entered and saw a Spiderman classic, so I left to get my Venom, when I went to fight Spiderman with my Venom he started evading, so I'm confused, is this a bug or is it something to do with that level, I have a 4/40 unduped Venom if that helps, also, I have a video if you want to see it, but I can't upload it here because it is too big and isn't the right file type, thanks for the help in advance!
